Note: There are two LEDs on the bottom of the OWC Thunderbolt 3 Dock near the front, which are not pictured. Their functionality is described below.

1. Data LED (green) — This LED will glow green when the dock has an active data connection to a computer via the Thunderbolt cable. If the computer is powered off or in sleep mode, this LED will power off.
2. Power LED (blue) — This LED glows blue when the dock receives power. Unlike some Thunderbolt devices, the Thunderbolt 3 Dock does not power off when disconnected from the computer or when the computer sleeps. As long as the dock receives power, the blue power LED will remain on.
3. SD Card Slot — accepts SD type media cards commonly used in digital cameras.
4. Combo Audio Port — accepts 3.5 mm microphones, headphones, and headsets.
5. High-power USB 3.1 Gen 1 port — Connect USB 3.1 Gen 1 devices here. This port is capable of providing up to 1.5A of power for charging devices such as the Apple iPad. Its functionality and performance is otherwise the same as a standard USB 3.1 Gen 1 port.

1. USB 3.1 Gen 1 ports — Connect additional USB 3.1 Gen 1 devices here. Left most port is a high power port. This port is capable of providing up to 1.5A of power for charging devices such as the Apple iPad. Its functionality and performance is otherwise the same as a standard USB 3.1 Gen 1 port.
2. S/PDIF Digital Audio port (output only) — Connect S/PDIF device here.
3. Gigabit Ethernet port — Connect an Ethernet cable here to access a wired network.
4. Thunderbolt 3 ports — Connect one port to the Thunderbolt 3 host; you must connect to the dedicated Power Delivery port (right) to charge the host. Use the extra port to connect up to five additional Thunderbolt devices, plus a display. Thunderbolt 3 supports DisplayPort™ 1.2 over USB-C™. The extra Thunderbolt 3 port can also be used to connect USB-C devices.
5. Mini DisplayPort — Connect your display here. This connection supports DisplayPort 1.2. See Section 2.2 Usage Notes
6. DC power input — Connect the included power supply here.

1. Connect the Thunderbolt 3 Dock to power using the included power supply and cable.
2. Connect the dock to a Thunderbolt 3 port on your computer using either one of the Thunderbolt ports on the dock.
3. Connect other devices to the appropriate ports on the dock. All connected devices will be available immediately for use on your computer

• Mac: To enable support for the Apple Super Drive, Apple USB Keyboard, and charging for iPad 1/2/3 generation devices on the dock’s ‘high-power’ ports, please install the Dock Ejector application for Mac. This application includes a driver that enables support for these devices and charging functions. go.owc.com/dockejector
• Windows: To enable support for 10G Ethernet you will need to install a driver www.owcdigital.com/support/software-drivers
• There is no power switch on the dock. As long as it is connected to power and to a computer, the dock will function. If the computer powers off or sleeps, the dock will remain powered on, but all other devices connected through the dock will power off or sleep, as if they were connected directly to the computer.
• The dock and all of its ports support hot-plugging. To ensure no data is lost, always eject or unmount any connected storage devices from your operating system before disconnecting them from your dock (or before disconnecting the dock from the host computer).
• The Combo audio port on the front of the dock is analog. The S/PDIF port on the back of the dock is digital, but it is output only.
• Thunderbolt 3 is backwards compatible with earlier versions of Thunderbolt when using the appropriate adapter, such as an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter. Use this type of adapter to connect a Thunderbolt 2 or Thunderbolt device to the Thunderbolt 3 Dock. Note: to avoid operating at reduced speeds, all Thunderbolt 3 devices should be at the front of the device chain, where TB3 = Thunderbolt 3, TB2 = Thunderbolt 2 and TB = Thunderbolt (e.g. TB3 Host > TB3 device(s) > TB2 or TB device via adapter > additional TB2 or TB devices).
• Thunderbolt device chains can support up to six Thunderbolt devices, thus five additional Thunderbolt devices can be chained to the Thunderbolt 3 Dock. A Thunderbolt 3 display (or a display connected via a USB-C display adapter) can be added to the end of a Thunderbolt 3 device chain.
• USB 3.1 Gen 1 ports are bootable only on mid-2013 and later Macs using macOS 10.12.2 or later. Thunderbolt and Ethernet are bootable on all Macs with a Thunderbolt port.
• Note that it is possible to connect other types of displays such as HDMI and DisplayPort to the available Thunderbolt 3 port, so long as you have the appropriate USB-C display adapter (e.g. you could use a USB-C to HDMI adapter, connected to the Thunderbolt 3 port).
• The Thunderbolt 3 Dock can support a single 5K display running at 60Hz.
• The refresh rates available at 4K will depend on the display connections used. To achieve 4K @ 60Hz on two displays, one display must be a native USB-C display and the other a native DisplayPort / mini DisplayPort display.
• Dual 4K display setups that include a native Thunderbolt 3 display were not available at the time of this writing. The Apple Digital AV Multiport Adapter and the Apple USB-C VGA Multiport Adapter are both supported by the Thunderbolt 3 Dock.

Begin your troubleshooting by verifying that the power cable is connected to the OWC Thunderbolt 3 Dock and to a power source. If the power cable is connected to a power strip, make sure that the power switch on the strip is turned on. Next, verify that both ends of the Thunderbolt 3 cable are properly plugged into the computer and the dock. If the dock is still not working properly, try using a different Thunderbolt cable or using another Thunderbolt port on the computer or the dock. You can verify if the dock is communicating with the computer by opening System Information and clicking on the ‘Thunderbolt’ category in the sidebar. If the dock is seen by the computer but one or more connected devices are not, troubleshoot each device individually. If problems persist, please contact OWC Support.
